Foreach loop prints to many values - php

Question

update, solved
I have the following 2 array's (with the same length), I want to display these values in a table. The problem is he prints just my first array ($gPositionStudents) and not the values of array $gPositionInternships.
The goal is to link each student to a different internship, but I know there is no relationship between these two array's. I'm looking for a function that can shift these 2 array's so that each time I shift the student has a other internship.
Importend to know, I did a small modification on array $gStartPositionInternship, I made this array equal in size as the length of array $gStartPositionStudents. With following code:
enter code here// Make items in $gStartPositionInternships as long as array $gStartPositionStudents
$gStartPositionInternships = array_pad($internships, $lengthStudentArray, 'null');
I included my current output, see image:
enter code here// Make table
$header = array();
$header[] = array('data' => 'Internship');
$header[] = array('data' => 'UGentID');
// this big array will contains all rows
// global variables.
global $gStartPositionStudents;
global $gStartPositionInternships;
$rows = array();
foreach($gStartPositionStudents as $value) {
foreach($gStartPositionInternships as $key=>$value2) {
// each loop will add a row here.
$row = array();
// build the row
$row[] = array('data' => $value[0]['value']);
$row[] = array('data' => $value2);
}
// add the row to the "big row data (contains all rows)
$rows[] = array('data' => $row);
}
$output = theme('table', $header, $rows);
return $output;

Answer 1

$rows[] assignment is inside the nested loop - it looks suspicious to me. Try to put that assignment after the nested loop, like this:
foreach($studentUGentID as $key=>$value) {
foreach($internshipNaam as $key2=>$value2) {
...
}
// add the row to the "big row data (contains all rows)
$rows[] = array('data' => $row);
}

Answer 2

Are your original arrays populated as expected ? Try print_f to figure it out. As far as I see if your original arrays have both 2 entries you should get a 4 entries array with like :
$rows = array(
[0] => array(
'data' => array(
[0] => array(
'data' => value
),
[1] => array(
'data' => value
)
),
[1] => array(
'data' => array(
[0] => array(
'data' => value
),
[1] => array(
'data' => value
)
),
[2] => array(
'data' => array(
[0] => array(
'data' => value
),
[1] => array(
'data' => value
)
),
[3] => array(
'data' => array(
[0] => array(
'data' => value
),
[1] => array(
'data' => value
)
)
)
)
is that really what you expect ?
